Arcena, Mylene Ross published the artcileThe effect of pulsed electric fields pre-treatment on the volatile and phenolic profiles of Merlot grape musts at different winemaking stages and the sensory characteristics of the finished wines, Name: Ethyl octanoate, the main research area is grape must winemaking sinapic acid rutin pulsed elec field.

This study investigated the effect of pulsed elec. fields (PEF) applied at different elec. field strengths (up to 41.5 kV/cm) and energy inputs (up to 49.4 kJ/kg) on the volatile and phenolic profiles of Merlot grapes at different stages of winemaking. Immediately after PEF treatment, greater amounts of anthocyanins and phenolics (e.g., catechin) were extracted while 2-hexenal (green aroma) was detected in lower concentrations in PEF-treated musts. At completion of alc. and malolactic fermentations, high-energy PEF treatment generally produced wines with increased anthocyanins, stilbenoids, hydroxycinnamic and hydroxybenzoic acids. A trained sensory panel assessed the sensory attributes of the finished wines using descriptive anal. It was found that those Merlot wines vinified with PEF-treated grapes possessed higher intensities of blackcurrant flavor and odor. The intensity of spice flavor in the Merlot wines also differed significantly between the wines. Overall, PEF treatment has the capability to provide winemakers the means to tailor the extraction of phenolic compounds towards the creation of red wines with distinct sensory characteristics.

Xu, Dan published the artcileImproving bread aroma using low-temperature sourdough fermentation, HPLC of Formula: 106-32-1, the main research area is bread temperature sourdough fermentation hydrolyzation.

To improve the aroma of bread, two aroma-producing yeast isolates from the Chinese liquor starter culture called Daqu, Meyerozyma guilliermondii CGMCC 17606 and Pichia kudriavzevii CGMCC 17607, were combined with Lactobacillus sanfranciscensis DSM20451, were used for sourdough fermentation at 10, 20, and 30°C. Volatile aroma compounds in bread crumb were extracted using headspace solid-phase micro-extraction and analyzed using gas chromatog.-mass spectrometry and gas chromatog.-olfactometry-mass spectrometry. Addition of sourdough fermented with mixed starters at 10°C promoted bread aroma, showed increased sensorial qualities. Acetic acid, 1-octen-3-one, and di-Me trisulfide, were most aroma-active compounds in sourdough bread fermented with M. guilliermondii and L. sanfranciscensis, whereas those in sourdough bread fermented with P. kudriavzevii and L. sanfranciscensis were acetic acid, 1-octen-3-one, 2-methoxy-4-vinylphenol, 3-methylthio-propanal, furfural, and 1-(2-furanyl)-ethanone. Reducing fermentation temperature to 10°C increased the formation of these key volatiles, as well as other aroma-active compounds,such as 3-methyl-1-butanol, 3-methylbutanal, 2-methyl-1-propanol, 1-octen-3-ol, isogeraniol, benzaldehyde, benzene acetaldehyde, Et octanoate, Et decanoate, phenylethyl acetate, furfural, and 2-pentylfurane. The amount of furans, pyrazines, and volatiles converted from amino acids in bread crumb also increased with protein hydrolyzation and amino acid formation in sourdough fermented at 10°C.

Wang, Yaqin published the artcileIn situ production of vitamin B12 and dextran in soya flour and rice bran: A tool to improve flavour and texture of B12-fortified bread, Product Details of C11H22O2, the main research area is bread vitamin B12 dextran soya flour rice bran.

This study aimed to develop a fermentation process that allows the concomitant production of dextran (a texture-enhancing agent) and vitamin B12 (in situ fortification) for bread applications. Mixed fermentation of soya flour or rice bran using Propionibacterium freudenreichii DSM 20271 and Weissella confusa A16 with added sucrose resulted in substantial quantities of dextran (5.6-5.8% dry matter) and B12 (7.9-8.9μg/100 g fresh weight), together with antifungal metabolites (e.g. acetic and propionic acids). In addition to an extended mold-free shelf life, the bread containing 50% (dough weight) fermented soya flour or rice bran not only contained adequate levels of B12 but also exhibited improved texture and sensory quality compared to the control, such as a higher loaf volume, a softer crumb, and a more cohesive and moister mouthfeel. The mixed fermentation reduced the beany or cooked-rice flavor but increased sour and cheesy flavours and aftertaste. Dextran produced during the fermentation process exhibited a masking effect on the beany and sour notes and aftertaste, consistently with reduced levels of green or grassy volatiles (e.g. hexanal, heptanal, (E,E)-2,4-decadienal, and 2-pentylfuran). Overall, the mixed fermentation method using P. freudenreichii DSM 20271 and W. confusa A16 showed potential for B12 fortification of bread products with high sensory quality.

Pico, Joana published the artcileSelection of the most suitable mixture of flours and starches for the improvement of gluten-free breads through their volatile profiles, Recommanded Product: Ethyl nonanoate, the main research area is gluten free bread teff quinoa flour starch volatile compound.

Abstract: Gluten-free breads have been characterised by a weak aroma. In this study, different mixtures of gluten-free flours (teff and quinoa) and starches (wheat and corn) were investigated by SPME-GC/QTOF with the aim of providing flours that potentially improve the aroma of gluten-free bread. Bread with the highest proportion of corn starch (60%) was discarded for its higher content in rancid volatile compounds from lipid oxidation, while bread with the highest level of wheat starch (60%) was discarded for its lower content of the key aroma 2-acetyl-1-pyrroline. Thus, the bread composed of 40% of each starch, 15% of quinoa flour and 5% of teff flour was chosen due to the higher proportion of pleasant volatiles from fermentation, 2-acetyl-1-pyrroline and pyrazines as well as the lower levels in rancid volatile compounds from lipid oxidation Moreover, it exhibited relatively dark crust, high volume and superior textural properties.

Guo, Sixun published the artcileAnalysis of tizoxanide, active metabolite of nitazoxanide, in rat brain tissue and plasma by UHPLC-MS/MS, Computed Properties of 55981-09-4, the main research area is brain plasma tizoxanide nitazoxanide UHPLC MS; UHPLC-MS/MS; brain tissue; nitazoxanide; tizoxanide.

Tizoxanide, the active metabolite of nitazoxanide, has recently been reported as an effective agent for the treatment of glioma. As there had been no report about the anal. of tizoxanide in brain tissue, we established extraction and UHPLC-MS/MS methods to quantify tizoxanide in rat brain and plasma to evaluate the brain-to-plasma ratio of tizoxanide. The biol. samples were mainly prepared by acetonitrile and the separation was performed on a Waters XBridge BEH C18 column. The mobile phase was composed of water mixed with 10 mM ammonium formate (pH 3.0) and acetonitrile according a gradient volume Tizoxanide and topiramate (internal standard) were monitored utilizing neg. electron spray ionization in multiple reaction monitoring mode. The methods were validated to be precise and accurate within the dynamic range of 5-1000 ng/mL and 0.2-50 ng/g for plasma and brain tissue samples, resp. The lower limit of quantitation of the method was 0.2 ng/g, which was far more sensitive than all existing methods to quantify tizoxanide in biol. samples. Application performed on rats exhibited that the brain-to-plasma ratio of tizoxanide ranged from 3.16 to 26.86% in 1 h after administration of 10 mg/kg nitazoxanide.

El-Kowrany, Samy Ibrahim published the artcileEvaluation of nitazoxanide as a novel drug for the treatment of acute and chronic toxoplasmosis, Product Details of C12H9N3O5S, the main research area is Toxoplasma nitazoxanid antiparasitic agent toxoplasmosis; IFN-γ; Immunohistochemistry; Immunomodulatory; T. gondii; iNOS.

For this purpose, mice were infected with 20 cysts (acute infection model) or 10 cysts (chronic infection model) of Toxoplasma gondii (ME 49 strain). Treated mice received NTZ (at doses of 100 and 150 mg/kg), starting from third day (acute model) or fifth week (chronic model) post-infection, which continued for 14 consecutive days. Effects of NTZ were evaluated in comparison to the pyrimethamine/sulfadiazine combination. Evaluation included mortality rates, brain cyst count, inflammatory scoring and immunol. studies. The latter included estimation of interferon-gamma (IFN-γ) and induced nitric oxide synthase (iNOS). In the acute infection model, NTZ at 100 and 150 mg/kg significantly reduced the number of brain cysts by 78 and 87% compared to the infected untreated controls and reduced the mortality rate to 24 and 20%, resp., compared with 44% in the infected untreated control. In the chronic infection model, cyst reduction reached 32 and 38% for 100 and 150 mg/kg NTZ treatments, resp. NTZ was significantly able to reduce inflammation caused by acute and chronic T. gondii infection with slight necrosis and few infiltrating mononuclear cells. Addnl., the immunol. anal. revealed that NTZ significantly increased the production of serum IFN-γ and enhanced iNOS production in brain tissue, suggesting an immunomodulatory role for the drug. Based on the findings of the present study, it can be concluded that NTZ is a potential drug for the treatment of acute and chronic toxoplasmosis.

Hanafy, Amr Shaaban published the artcileChallenges in covid-19 drug treatment in patients with advanced liver diseases: a hepatology perspective, Synthetic Route of 55981-09-4, the main research area is review human COVID drug treatment advanced liver disease hepatol; Advanced liver disease; Anticoagulation; COVID-19; Cirrhosis; Coagulopathy; Drugs.

The global incidence of coronavirus disease 2019 (COVID-19) continues to increase despite health care efforts. The disease is caused by coronavirus 2 with high transmission and mortality rates. Little is known about the management of COVID-19 in advanced liver disease. The aim of work was to propose a plan for management of this drastic disease in case of this specific population with review of medications that could be suitable for advanced liver disease. All the guidelines and medications available for treatment of COVID-19 were reviewed with selection of the less toxic medications that could be used in advanced liver disease. Drugs suitable to manage COVID-19 in patients with liver disease might include remdesivir i.v., nitazoxanide + sofosbuvir, ivermectin, tocilizumab, convalescent plasma, and low mol. weight heparin in certain situations. Advanced liver disease is associated with portal hypertension and splenomegaly with reduction of blood elements and immune dysfunction and impaired T cell function. Thus, when confronted by cytokine storm as an immune response to COVID-19, there may be an increase in the mortality rate of these patients. Through this review, a plan to treat COVID-19 in this special group of patients with advanced cirrhosis is proposed.

Gong, Di published the artcileA comparison of postharvest physiology, quality and volatile compounds of ‘Fuji’ and ‘Delicious’ apples inoculated with Penicillium expansum, Safety of Benzyl acetate, the main research area is apple Penicillium expansum firmness volatile compound.

Blue mold caused by Penicillium expansum is a major postharvest disease of apple fruit, which leads to fruit loss and patulin accumulation. In this study, ‘Delicious’ and ‘Fuji’ apples were inoculated with P. expansum to investigate effects of infection on physiol., quality and release of volatile compounds The results showed that P. expansum significantly promoted ethylene production, increased respiration rate, and induced higher peaks of ethylene and respiration in fruit. The fungus also caused a lower of membrane integrity, firmness, and the content of total soluble solid and titratable acid. Moreover, P. expansum increased the content of volatile compounds in two cultivars of apple. C6 alc. and aldehyde contents were significantly improved by inoculation in the earlier storage stage, and ester contents were improved in the middle and later storage stage. According to PLS-DA anal., hexanoic acid and hexanal were the most important factors to distinguish the inoculated ‘Delicious’ and ‘Fuji’ from their controls. Interestingly, among specific volatile compounds detected in the two inoculated cultivars, 3 volatile compounds, including phenethyl acetate, Me 2-methylbutanoate and Et benzeneacetate, were common in both of inoculated fruit. Although wounding increased ethylene production and respiration rate, decreased quality of the two cultivars and affected volatiles release, the effects were less than P. expansum. Compared with ‘Fuji’, the inoculated ‘Delicious’ had a higher of lesion diameter, ethylene production and respiration rate and content of total soluble solid, and a lower of membrane integrity, firmness and content of titratable acid. The inoculated ‘Delicious’ also released more volatile compounds, especially C6 volatiles. In general, P. expansum inoculation promoted ripening and quality loss, leading to change of volatile compounds during storage and release of specific volatiles. Moreover, ‘Delicious’ was more susceptible to P. expansum than ‘Fuji’.
